Ok, this works, and seems to copy in to out on all channels.

Still trying to understand that. Could you give a practical
example ? Say e.g. that I want to play t2.wav and t5.wav to
outputs 2 and 5, and record from inputs 1 and 6 to t1.wav and
t6.wav. This emulates an 8-track machine playing back two 
channels and recording two others. How would that be done ?

Many thanks for your help.
